Someday, Someday, Maybe by Lauren Graham
Look! Lorelai from Gilmore Girls wrote a novel! Okay, it's written by the actor who played Lorelai, but whatever. I will continue to refer to it as "that book by Lorelai."
Apparently, Lauren Graham used her own experiences trying to become an actress in New York as inspiration for this fun story. It's funny and fun and sweet and enjoyable. I liked it a lot.
